-Run a can of Chevron “Techron” through it. Follow the instructions…put it in a full tank and run it as far down as you’re comfortable before filling up (diluting).
-are all fluids up to date? (Engine oil, transmission etc)?
-Tires up to pressure? (34 or so cold). Are the tires bigger than stock size, or more aggressive/heavier?
-any aero drag? Rooftop cargo box?
-any big hills (like mountain ranges) on your route?
-Easy driving should net you between 400 and 500 miles per tank, if your model year’s tank capacity is same as current year’s.

I‘m getting (calculated) 30 when I’m at 90/10 freeway/city on my 2023 Limited (2.5 engine). Shows more like 31-32 on the display. I drive like an old man though…easy starts, no jackrabbiting, and rarely over 72-75 mph.

Good luck, and report back

Gonna try it. I do live in the Catskills. Normal speed average is around 70. Only a 10 minute jaunt to work though.

I bet that short commute contributes mightily to your poor (ish) fuel economy.
Engine is barely up to efficient operating temp that quickly, and the benefits of freeway economy really aren’t seen, even though you’re on a freeway.

Have you done a longer road trip yet? My guess is you’ll see much better numbers, specially if you do the other items listed above.
